Hey guys!

I have played through all the main plot WC titles and I'm currently on WC: Prophecy, but I have a little problem with controls.

I am playing it with keyboard+mouse, so I am maneuvering the ship and firing my guns with mouse, but when it comes to missiles, I still have to use Enter for that. Problem is, that by some bug or something, the "firing guns" action is configured with Enter as well, so I cannot fire guns and missiles independently.
It causes me some trouble in space fights, mostly when I am firing with charging mass drivers, because I cannot "keep" the cannons charged - as soon as I fire the missile, they discharge themselves and I waste the gun energy for nothing. Firing missiles via mouse is also impractical, because in order to do it, one has to first click'n'hold the RMB and then click the LMB, but it doesn't work the other way - so no missiles when firing guns for me.

Is there any patch or fix for this? Or should I borrow a joystick just to play this game or what?
I am afraid to play it with keyboard only - I don't have a good experience with it at previous WC titles.
